The hood 16 is provided with an aperture i9 preferably located centrally with respect to the hood 6 and formed by an upturned lip 20. Support means 2: for a light source 22 is adapted to be detachably positioned in the taperture 9 to position the light source 22 within the chamber 8. The support means 2 and its means of connection in the light fixture will be more completely described hereinafter. As can be seen in FIG. 1, the light source 22 is sup ported in the chamber 8 so that the hood 35 extends be low the light source 22. The hood 6 then provides a reflector for reflecting the upwardly directed light from 4. Where automatic operation of the light fixture assembly is desired a photocontrol may be included, and in accord ance with our invention is included in the light Source support means 2 which then constitutes a unitary light socket-photocontrol assembly. The photocontrol 38 can then be positioned at the top of the light fixture assembly A for most efficient control and further becomes an in tegral part of the light fixture assembly . A problem which heretofore has existed and which prevented the 0. incorporation of a photocontrol 38 and a light Socket as Senably 39 into a unitary assembly, is that the photocon trol being essentially a thermally actuated Switch would be adversely affected by heat which is generated by the the light Source 22 onto the ground and the lower edge of light source 22. This, even in view of the fact that many the hood 6 provides a cutoff to reduce the amount of 5 photocontrol switches are provided with ambient tempera glare to an observer. The light diffusing member 7 fur tire compensation, because the heat generated by the light ther contributes to the reduction of glare and the proper source greatly exceeds any possible ambient temperature distribution of light onto the ground. rise and will adversely affect the operating characteristics The support arms 7, 7 and 7' extend upwardly and of the photocontrol assembly. Further, the photoelectric outwardly from the slip fitter 4 to engage and support the 20 ce; itself is adversely affected in that the materials used hood 6 in spaced relation from the slip fitter 4. Fixed therein are sensitive to and will deteriorate upon undue to the top of each of the support arms, as by means of a exposure to high temperatures, as will many of the other rivet, is a clip 23. Finger screws 24 extend through the photocontrol components. Hence the operating life of hood 16 and engage each of the clips 23 to fixedly attach the photocontrol would be greatly reduced if exposed to the hood 6 to the tops of the support arms. As can be high temperature for prolonged periods. To overcome seen in FIG. 7, each of the clips 23 is provided with a these problems we have provided means, disposed be pair of opposed wing-like projections 26.

A gasket 25 is provided Although the particular design of the photocontrol as at the juncture of hood and diffuser to provide a bug 30 sembly 38 forms no part of this invention a brief de proof seal. scription thereof will be made. Referring to FIG. 3, The lower ends of the Support arms engage the body temperature sensitive switch means including a fixed con 8 of slip fitter 4 with one of the Support arms 7 being tact 4C and a movable contact 45 fixed to an over-center fixedly attached to the body 8 and the remaining two Sup Snap-action switch element 42 is provided.

A second bi-metal 45 is as suitable apertures 27 provided in the body 3. Two of the sociated with the switch element 42 to provide com apertures 27 are dead ended holes (not shown) whereas pensation for normal variations in ambient temperature. the third aperture, as illustrated in FEG. 5, is a through 40 A fine electrical resistance wire 43 is Wrapped around hole. The means for fixing the support arm 7 relative to the bi-metal 44 to provide means for supplying heat to the body 8 consists of a bushing 28 which fits into the the bi-metal 44. In a manner well known in the art, a lower end of aperture 27 and wedges the support arm 7 pilotoelectric ceil (not shown) is connected in series with against the wall of the aperture 27 to hold that arm in a resistance wire and controis the amount of electricity fixed relation with the body 8. A notch 29 in the arm 7 supplied thereto in accordance with the amount of light and a notch 3; in the top of the body 8 provide means 45 falling on the photoelectric cell. for visually indexing the support arm 7 in the assembly. Thus it can be seen that by placing the photocontrol Similar indexing means is provided for each of the other 33 and the light socket 39 in a unitary assembly the support arms, however only one has been illustrated. The danger exists that the switch in the photocontrol 38, be support arms 7 and 7' are releasably fixed in position ing a temperature sensitive switch, will be affected by relative to the body 8 by means of set screwS 32. When heat generated by the light source 22 and interfere with the set screws 32 are loosened the arms 7 and 7' can be the consistent operation of the photocontrol assembly; rotated to nest compactly with the fixed arm 7 as is illus and further the heat generated by the light Source will trated in FIG. 6.
